Abstract (en)

[origin: DE19821624A1] The projection screen (10) has a projection plane (30) formed of segments (11). At least one segment is a sound radiator segment (11') for emitting sound waves from the projection plane. The segments are connected to each other by connecting elements on their edges. The segments are formed of a core layer and a covering layer. The low-frequency segments are arranged in the middle of the projection screen.
